2 fish purchased by the DNR for stocking.
Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

DNR fish survey, 2025
Temperature and dissolved oxygen measurements were collected from the deepest basin in Little Long Lake on August 1st, 2025. This was done to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee, the most sensitive coldwater species present in this lake. Cisco require a layer of oxythermal habitat that contains water temperatures below 21.2 degrees C (70.2 degrees F) and dissolved oxygen concentrations above 3.0 mg/L. Based on data collected from the deepest basin (maximum sampled depth was 42.6 feet), the water temperature decreased to 21.2 degrees C (70.2 degrees F) at 18.1 feet and the dissolved oxygen concentration decreased to 3.0 mg/L at 32.3 feet at the time of sampling. This layer in the water column was 14.2 feet, indicating oxythermal habitat for Cisco was present. Further, the temperature at which dissolved oxygen decreased to 3.0 mg/L (i.e., TDO3, a single variable to characterize oxythermal habitat) was 9.1 degrees C (48.4 degrees F). TDO3 values cooler than 21.2 degrees C (70.2 degrees F) indicate that oxythermal conditions were suitable for Cisco at the time of the survey. Data collected by the Minnesota Department of Natural Resources during the period of maximum oxythermal stress (July 26th to Aug 24th) in 2015, 2022, 2024 also indicated suitable oxythermal habitat in all years surveyed, with the least favorable conditions recorded in 2024 when the suitable oxythermal habitat layer was 13.1 feet thick. When adequate oxythermal habitat is not available, Cisco are squeezed into unfavorable, warmer water conditions and experience higher levels of stress. Little Long has been surveyed with fisheries gear fairly consistently since 1975, and only one Cisco has been caught since 1994 which coincides with a substantial increase in Walleye catches in survey nets.
